I have set up a GIF animation with 81 frames. I set the "Repeat" selection in "Animation Properties" to "Repeat 1 times". However, the animation keeps repeating (looping) in the preview and doesn't ever stop. What am I doing wrong?

PS: The lowest value that I can set for the 'repeat value' is 1. Shouldn't it really be able to repeat "0" times?

Has anyone figured out a fix for this besides making the last frame duration long? Even though I set it for repeat of 1 or 2 times, it continuously repeats without stopping. Making the last frame duration long won't work in this situation.
